"I’m pretty happy with the state of things now. I have to admit that in
the beginning, I was cursing loudly asking for my desktop and panel
back, but I’m used to the dash area and window picker now. The search
feature (which is similar to Spotlight in OSX) is really useful and I
end up using that for the majority of my tasks. I also find the
notification system very well done along with the ability of dealing
with messages without changing windows. In the end, all I can say is I
find myself using Fedora more over my pretty MacBook Air for the
majority of my tasks."
